Be' it knownl that I; CHARLESQRLLMV', ci citizen off the 'nitedffStes?,v residi'nzg'l at Sllateot" Louisiana, have-"invented certain.

new and useful Iinproveinentsin fReiailiiig designedto beu'se'd forreplacing the? trucks ofl derailed' railway carsontojtlie track.

Another 'object of theUv iii'vention: is' to pro'-y vide speciallydesigned frogs tjob'e used" in pairs for replacing triielts of` cars,.which have been detailed", ontoY the" tracks from veither side. v 'lAnotherV object of the .intenti-onf is topi-'o'- vide replacers, orfrogs of the character Adescribed: which"y are comparatively' light'vso* that they'l can be easily" harrdled by one person. and whose" parts'are so' arranged" and proportionedIx that theyI wil-ibestr'ong. andE notliable' to break-age and furthermore will" be liable to be displaced thecardwlieel's" duringu theV rerailin'g op'eratibn'-.` ,l

With' the'- above landt other" objects in view the invention has fparticular relati'oii'to cer'- tain novel features ofconstruction,operationl and arrangement of parts, an example of which is given inthis specific''ation41 and illustrated in the accompanying drawings,

wherein:

Figure 1 shows a plan view of the section of the railway track showingtwo pairs, or sets of the replacers in position for replacing the trucksof derailed car from either side of the track.

Figure 2 shows a plan View of the outside frog.

Figure 3 shows a sectional view thereof taken on the line 3, 3 of Figure2.

Figure 4 shows an inside view of the outside frog.

Figure 5 shows a plan view ofthe inside frog.

Figure G shows a front end view thereof.

Figure 7 shows an outside View thereof, and,

Figure 8 shows a bottoni plan view 0f said frogs.

Referring now more particularly to the drawings, wherein like numeralsof reference designate similar parts in each of the formed with4 a veivof the rib 12.

figures, the numeral v1 represents' t way ties and the niiin'eral's 2",d'lesignatetlref railfs thereon".` The "niinierzl 3' desi'g'n'ate'stliebody of 'the outside frog and the", .i I

The tops of" the; frogs incline"upwardly from their Vr'e'a'lrtlo theirforward ends. TheA outsidie frog"E has a? C lit'rgolial upstanding ribl0, wlioseyrear end i'ssp'aced fronifthefrail and ywhose forward endis'turned'intov alignni'ent with the' rail andfforinsftlie"'forwa1cllyscribed are cast integral, excepting the teeth 8 which may be `driveninto suitable sockets provided for them.

In use, a set or pair of the frogs is positioned in front of the wheelsto be re placed. The pull on the car is exerted along the cent-ral lineof the track and the flanges of the outside wheel pass up along theinner side of the rib 10, the flanges of the inside wheel passing upalong the inner side Said wheels are thus gradually elevated and movedover into align` uol lli)

ment above the .tracks or rails, thc wheel treads gradually assuming aposition, one on the rib l5 above one rail, and the other on thesupplemental tread 13 above the other rail and said wheels then movedforwardly, gradually moving down onto the rails over the decliningprojections l1 and 14, without any considerable jar and withoutdisplacing the replacers. It often happens that the trucks at one end ofthe car will be derailed on one side and the trucks at the other end ofthe car will be derailed on the other side, the car thus standingdiagonally across the track. In such case two pairs of replacers will beused and positioned as shown in Figure l. Both the front and rear trucksmay be thus simultaneously replaced on the track at one op` eration.

lt often happens that only the rear pair of wheels in a truck becomederailed and conditions will not permit placing frogs between thederailed wheels and those remaining on the rail. ln such ca-ses the re`placers are placed ahead of the wheels remaining on the rail. lVith theforward vmovement of the car the wheels pass over the re-placers, thewheel flange, on side of truck Where inside frog is placed, passingthrough the groove 15 between the rib 19. and the supplemental tread 13which is oli'- set thereto. On the outside frog the overlying flange 5,the upstanding rib 10 and the extending projection ll maintain thealignment of wheel with the rail. With the passing of the forward wheelsover the frogs, the derailed wheels following are picked up anddeposited on the rail.

What l claim is l. Car replacers including two members having upperinclined faces and formed at corresponding sides to engage over thetreads of the rails of la railway track, a

single diagonal upstanding rib formed on the upper face of one member,whose upper end is turned into alignment with the underlying rail andextended forming a declining forward projection, said rib and projectionforming a continuous tread for the car wheels, an npstanding rib formedon the upper face of the other member parallel with the adjacent rail,and a supplemental tread formed on the last lmentioned member and olfsetwith respect to said last mentioned rib and aligned with the underly`ing rail and extended forming a declining forward projection. Y

2. Car replacers including two members each formed of one piece andhaving upper inclined faces, integral lugs formed at corre- -spondingsides of the member to engage over the treads of the rails of a railwaytrack, Ia diagonal upstanding rib formed on the upper face of onemember, whose upper end is turned into alignment with the underlyingrail and extended forming a forward projection, said rib and projectionforming a continuous, smooth wheel tread, an upstanding rib formed onthe upper face of the other member parallel with the adjacent rail,and-a supplemental tread Vformed on the last mentioned member alignedwith the underlying rail, the rear end of the supple'- mental treadbeing spaced laterally from the forward end of the last named rib andsaid supplemental tread being extended forming a forward projection,said projection declinino forwardly.

In testimony whereof l hav-e signed my name to this specification in thepresence of two subscribing witnesses.
